Plants were grown in hydroponics for three weeks plus 12 d in control medium without NaCl. Normalized transcripts of the control treatment were compared between cultivars. Membrane protein transcripts that showed ≥2-fold differential expression between salt-tolerant FL478 and salt-sensitive IR29 are listed.
